(Cl. 22m-lee) 3 Claims.

This invention relates to a shower head and more particularly it is concerned with a novel form of head in which the structure features a substantially elongated tubular casing preferably having several sets of discharge apertures in which the said apertures may be of different sizes so that by rotating the tubular casing selectively either one of the sets of apertures may be so positioned as to permit fluid fiow therethrough at will, thereby making the shower head desirably adjustable for fine, medium, or coarse streams.

Another important object is to provide for a shower head construction in which the tendency to clog will be substantially minimized.

A further object is to provide a structure in which the spread of the discharge streams remains substantially constant insofar as the length of the head is concerned and increases in its transverse spread proportionate to the distance from the head, thereby producing a shower pattern substantially of body width.

Other objects and advantages will become more readily apparent upon proceeding with the specication read in light of the accompanying drawings, in which Fig. 1 is a fragmentary sectional assembly view of a preferred embodiment of our invention, while Fig. 2 is an end exterior view.

Fig. 3 is a transverse sectional assembly View taken on the line 3 3 of Fig. l.

Fig. 4 is a transverse fragmentary sectional assembly view in a modified form, and Fig. 5 is a transverse sectional view taken on the line 5-5 of Fig. 4.

Referring now to Fig. l, a 'T fitting, generally designated I, is provided having the usual inlet tubing 2 connected with a source of water supply (not shown) and with the flow passage 3 suitably connected, as at i, to the said fitting. Oppositely disposed and preferably, although not necessarily, in axial alignment, the discharge tubes 5 and 6 are provided. For ease of assembly, the said tubes are maintained in suitable leakproof relation to the fitting I by means of the threaded gland 8. In order to maintain the end portions 9 of the tubes 5 and t in spacedapart flow-permitting relation after assembly with the fitting, a suitable set screw II or other spacer member is positioned therebetween to function as a stop, as indicated. At the opposite end portions, the tubes 5 and E are threaded as at I2 to the respective end heads I3, the heads being of substantially elongated form as shown more clearly in Fig. 2. Each head member is tapped as at I4 with the threads as shown to surface of the split sleeve 28.

thereby receive in leakproof relation the non-rotatable slotted inner tubing or pi e l5, the latter member being slotted for substantially its entire length, as at I6, except for that portion necessary to provide a leakproof connection and to receive the end closure members I'I as hereinafter referred to in more detail.

Snugly fitted around the slotted tube I5 at each end portion thereof are the said end closures suitably attached in non-rotatable relation to the outer apertured sleeve I8, as indicated at i9. An end thrust washer 2l is received within each threaded end closure member Il thus serving as an end bearing for the packed bushing or spacer 22, the latter member preferably being recessed as at 23 to receive the packing 24 thereby to effectively seal the tubing periphery 25 against the escape of liquids outwardly beyond the end portion of the rotatable end closures or caps Il. Preferably also on its outer periphery, the packed member 22 is annularly recessed, as at 2S, thereby to provide for an annular chamber between an end portion of the outer sleeve I8 and the member 22 to receive the packing 2l, thus holding the member 22 in relatively fixed axial position, and rotatable with the outer sleeve I8 and the end closure Il.

Fitted within the interior periphery of the sleeve I8 is the sleeve 28 which being split for its entire length, as more clearly shown at 29 in Fig. 3, allows for the member 28 to be sprung slightly outwardly and therefore relatively snugly received within the sleeve I8. The inner slotted tube I5 being non-rotatably mounted relative to the sleeve i3 permits the split tubular member 28 to be held non-rotatably also by means of the eccentric ring 3l which is held nonrotatably upon the tube I5 by means of the headless set screw 32. It is also attached as at It by solder or other suitable means to the interior The eccentricity of the member 3| and such method of attachment permits ease of assembly and adjustability in positioning it xedly relative to the stationary members I5 and 28. It also allows for the member 23 having the inner chamber 33 to be outwardly sprung without being adversely adected by the ring SI.

As shown more clearly in Fig. 3, the outer sleeve member I8 is suitably apertured with three sets 0f holes, each set preferably having a different size of hole as indicated at 35i, 35, and Se, respectively. The size, shape, and the manner of providing for such apertures is optional depending upon the service conditions for which the shower head is ultimately intended. Thus, the discharge of liquids from the chamber 33 is easily controlled by predetermined rotation of the end threaded closure heads l1 relative to and upon the split tube 28, the outer sleeve I8 being rotatable in either direction to permit the desired flow through the respective sets of apertures as elected.

Referring now to the modied form of the invention shown in Figs. 4 and 5, in which a relatively more simple arrangement is shown of a novel tubular shower head.

The head may be mounted in the usual manner to the wall generally designated 3l and being connected to the usual source of fresh water supply (not shown) by means of the threads 38, the tubing 33 being suitably formed in the desired manner to accommodatethehead assembly as hereinafter described in greater detail.

It will be noticed that the tubing 39 is-piovided with the straight portion generally designated 1H, andthe straight tubular section at its lower portion is slotted as at 42, which is shown more clearly in; Fig. 5. Snugly tting around the outer periphery of the straight portion Gl ofthe tubing 39 is the outer sleeve 43, one end of the tubing being threadedas at i4 to receive the tapped member 45, the latter having the inner annular recess 46 to receive the O-ring il, the latter member serving the purpose of providing a iiuid tight seal against any escape of water from the end of the sleeve 43.

At its opposite end, the sleeve member is threaded as at 48 to receive the combined cap and rotating handle 49, the latter forming in connection with the gasket i a uid tight seal with the ends of the sleeve @23. Rotation of the member 4t rotates the sleeve 43 to place the latter in desired relation to the slot i2 for reasons previously referred to.

As indicated in Fig. 4, at its lower end portion and preferably in spaced apart relation thereto as shown in Fig. 5, the sleeve 43 is provided with series of discharge apertures 52, 53, and {il} respectively, which upon predetermined rotation of the outer sleeve 43 may be brought into .suitable registration with the elongated slot G2 of the straight portion GI of the tubing 3G to result in the desired discharge spray or stream.

In order to secure the outer sleeve 43 to the straight portion fil of the tubing Si! more effectually, a groove 55 is provided in the tubing straight portion fi! engageable by the set screw 55 threadedly received within the straight tubing fil as indicated and projecting within said annular recess 55 to permit rotation while inhibiting longitudinal movement of the-sleeve 43 and its assembly upon water pressure being applied to the interior or" the tubing 39.

Preferably, but not necessarily, a screen 5? may be used which is attached to the interior of the tubing at opposite ends of the slotted portions as indicated at 58 and 53, respectively, by means of a conventional soldered or sweated connection or any other form of iluid tight arrangement. It has been found that under certain conditions of installation that positioning theY screen 5? between the annular space thereof, as at i, improves the form of the discharge fluid through the respective apertures 52, 53, and 54 apparently due to the breaking up of the body of water into particles to aid in their passage while moving through the said apertures of the sleeve 43.

Thus, it should be apparent that a relatively simple and emcient shower head has been pro-y 4 vided, having a high degree of flexibility in its performance and capable of covering a desirably shaped area in the surface defined by the discharging streams.

It should also be understood that only a pair of preferred embodiments of our invention have been shown and described, and it is, therefore, obvious that substantial changes and modiiications may be made falling within the scope of the appended claims.
